Glaucoma

Glaucoma is a group of diseases of the optic nerve involving loss of retinal ganglion cells in a characteristic pattern of optic neuropathy. Although raised intraocular pressure is a significant risk factor for developing glaucoma, there is no set threshold for intraocular pressure that causes glaucoma. One person may develop nerve damage at a relatively low pressure, while another person may have high eye pressures for years and yet never develop damage. Untreated glaucoma leads to permanent damage of the optic nerve and resultant visual field loss, which can progress to blindness.

The definition of Glaucoma?

User Avatar

Asked by Wiki User

Glaucoma is a group of eye conditions that can damage the optic nerve and lead to vision loss. It is often caused by high pressure inside the eye, which can damage the optic nerve over time if not treated. Early detection and treatment are important to prevent vision loss from glaucoma.

Secondary open angle glaucoma (including pigment dispersion, pseudoexfoliation). Another differential is Ocular hypertension.

Can a dog take Benedryl if they have glaucoma?

User Avatar

Asked by Wiki User

For the most part, no. Dogs with allergies tend to have skin and gastrointestinal tract issues, not the upper respiratory signs shown by humans. Therefore, giving a dog Benadryl to reduce allergy-related inflammation is probably not going to do anything to resolve an eye issue. However, a veterinarian who has examined your dog and determined the cause of the eye issue may prescribe Benadryl for your dog.

Can alcohol cause glaucoma?

Asked by Wiki User

Drinking alcohol does not seem to be related to the development of glaucoma. It is most common in people who have a family history of glaucoma, people who are nearsighted or diabetic, people suffering from other diseases of the eye and those who smoke.

Which is worse Glaucoma or Cataract?

User Avatar

Asked by Wiki User

Cataracts: loss of transparency in the lens or rather the lens are clouded due to changes in the structure of lens' proteins and this due to excessive exposure to ultraviolet rays

Glaucoma: a buildup of aqueous humor within the anterior cavity, there is also an abnormally high intraocular pressure

What are sympthons of glaucoma?

Asked by Wiki User

First of all you have misspelled symptoms.

Primary Open Angle Glaucoma, which is what I am assuming you are inquiring about, is the most common type of glaucoma. Unfortunately, there are no symptoms. This is why it is important for people to get their eyes checked on a regular basis especially if you are over the age of 40 and have a positive family history of glaucoma. Optometrists can detect glaucoma through 3 main checks.

First of all a field of vision check would reveal any glaucomatous field defects, usually starting at the nasal field and progressing in an arcuate pattern to the optic disc. If left untreated the eventual consequence of this would be tunnel vision.

Secondly, an assessment of the optic nerve head can reveal glaucoma. If the cup appears very deep or the optic nerves are asymmetrical between the 2 eyes then this can be indicative of glaucoma. A pale disc is also a sign. As is thinning of the neuro-retinal rim and splinter haemorrhages at the disc, usually in the inferior nasal quadrant.

Finally, an optometrist will check the intra-ocular pressure of the eyes. Asymmetry of more than 5mmHg or a value over 21mmHg can suggest glaucoma. This is the least reliable measure of glaucoma detection as you can have normal IOPs yet suffer from glaucoma.

Is there treatment of glaucoma with acupuncture?

User Avatar

Asked by Wiki User

The treatment of Glaucoma is to reduce the eye pressure (IOP). Eye drops and surgery would be effective for this purpose.

Glaucoma medications are either oral or topical. Topical medications such as eye drops, eye ointments, or inserts work to reduce IOP either by increasing the outflow of fluid from the eye or by reducing the amount of fluid produced by the eye. These include:

- Miotics increase the outflow of fluid. These include Isopto® Carpine, Ocusert®, Pilocar®, and Pilopine®.

- Epinephrines increase the outflow of fluid. These include Epifrin® and Propine®.

- Beta-blockers reduce the amount of fluid. These include Betagan®, Betimol®, Betoptic®, Ocupress®, Optipranalol®, and Timoptic®.

What is the red bump in the corner of your eye?

User Avatar

Asked by Wiki User

It sounds like you are describing a pinguecula and it is caused by prolonged exposure to ultraviolet (UV) light. (ie-spending too much time outdoors without wearing sunglasses) We see this more commonly in the southwest region of the USA and for some reason Hispanics tend to develop them more rapidly than caucasians.

There is no form of treatment unless it progresses to a pterygium. As the pterygium grows and gets close to the center of your vision, it can be removed with a surgery. But it's always best to never let it get to this point.

I recommend looking these two things up on Google pictures and you will have motivation to wear sunglasses outside to prevent the pinguecula from converting into a pterygium.

What does it mean when you see a circle in one eye?

User Avatar

Asked by Wiki User

You would do yourself a good deed by calling your eye doctor. Not sure if you mean you see a halo looking circle or dark small spot that moves when you look at a white background. It's probably floaters if it seems to move around when you try to look at it. They say you shouldn't try to focus on it.

What is glaucoma due to?

User Avatar

Asked by Wiki User

Glaucoma occurs if the aqueous humor is not removed rapidly enough or if it is made too rapidly, causing pressure to build-up. The high pressure distorts the shape of the optic nerve and destroys the nerve.

Can fluocinolone acetonide topical solution cause glaucoma?

User Avatar

Asked by Wiki User

I lost nearly 3/4 of my hair. Fluocinolone topical was the 4th topical I was prescribed. I used it for about a week before the hair loss started. By the time the doctor figured out it was the medicine the damage was already done. They switched me to a different topical steroid and the hair loss stopped. I had waist length blond wavy hair.
